To all whom/it may concern:

Be it known that I, FnANK'BnsALn, citizen of the United States residingat C0- shocton, in the county of Coshocton and State of Ohio, haveinvented certain new and useful Improvements in Double-Facers, of whichthe following is a specification.

This invention relates to machines for applying facin" to corrugatedpaper and more particularly to a machine for applying a second facingsheetto single faced corrugated paper. 1

The object of the invention is to provide a machine of simple anddurable construc- 3 5 tion, by means of which one or more facing sheetsmay be applied to a corrugated strip and the composite sheet cut intopredetermined lengths at one operation of the inachine.

A further object is to provide a facing machine, the construction ofwhich is such that both sides of the corrugated strip are heated andheld in contact with the facing strip during the passage of said stripsthrough the machine thus preventing cupping of the resultant product andproducing a smooth straight. composite sheet.

A further object is to provide a cutting device including an oscillatingframe having 3 a blade mounted for reciprocation thereon and operativelyconnected with the strip feeding mechanism, said cut-ting device beingactuated intermittently to cut the double faced corrugated strip intopredetermined lengths.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefliciency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted. to within the scope of theappended claims. 7

For a full understandin of the invention and the merits thereof an alsoto acquire a knowledge of the details of construction and the means foreffecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a side elevation of a double facing machine constructed inaccordance with my. invention; Fig. 2 is a longitudinal sectional 'viewof the same; Fig. 3 is a plan view; Fig. 4 is a transverse sectionalview taken on the line 44 of Fig. 3; Fig. 5 is a perspective view of thecutting-mechanism and the adjacent portion of the supporting frame.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views 0 the drawings by the same referencecharacters.

The machine forming the subject matter of the present invention isprincipally dcsigned for applyin a second facing to a corrugated strip ator the latter has been passed through a corrugating machine and thefirst facing appliec thereto.

The machine comprises a supporting frame including spaced side walls 5having depending feet 6 bolted or otherwise rigidly secured thereto andupon which is mounted a casing or housing 7.

J ournaled in the side walls 5 of the sup porting frame, are a series ofspaced horizontally alined feed rollers or c linders 8, the latter beinhollow and pre erably extended the entire width of the casing 7, asshown.

Disposed beneath the feed rollers 8 and preferably arranged in verticalalinement therewith,are similar feed rollers 9, whichin conjunction withthe rollers 8 serve to press the facing strip in contact with thecorrugated strip as said strips are fed through the machine.

The upper and lower feed rollers 8 and 9 are hollow to provide steamchambers 10, in order that the rollers may be kept at the proper temerature to insure drying of the paste or ot er adhesive material appliedto the corrugated strip.

Each feed roller is provided with oppositely disposed spindles 11 whichproject through bearings 12 in the side walls 5 of the supporting frame,there being suitable pockets 13 formed in the side walls 5 ber neath theprojecting end of each spindle 11. The up r ends of the pockets 13 areopen, while t e lower ends thereof are provided with threaded aperturesfor the reception of set screws It by means of which the distancebetween the adjacent rollers may be regulated so as to accommodatestrips of paper of different thicknesses.

The spindles 11 on one side of the machine are rovided withiongitu'dinal openings whic communicate with the steam chambers '10 andin which-are seated the. sleeves or bushings 1 5 of suitable sprocketwheels 16.

be bushings 15 are secured to the adjacent Steam supplied to thecompartments 10 of the several drums r rollers 8 and 9 thrrugh pipes orconductors 18, two of which are preferably ,citt'ndcd through eachbushing to. One of the pipes 18 of each drum or roller is connected witha main supply pipe it), while the other pi pc 18 is connected with anexhaustpipe It so that the steam enterthrough the pipe 19 is free tocirculate within the compartments it) and exhaust into the pipe :20,there being a suitable steam trap 21 operatively connected with thepipes 19 and at the forward end of the machine, as shown.

Disposetlwit-liin the casing or housing 7 and interposed between thefeed rollers or drums, are steam chests. the abutting faces of the steamchests being flat and unobstructed and spaced apart to permit thepassage of the corrugated strip and facing strip through the machine.

The steam chests 22 are connected by branch pipes 23 so as to allow acontinuous circulation through the several steam chests for the purposeof maintaining the latter at the proper temperature, steam being admit.-ted to the upper and lower steam chests at one end of the machinethrough a pipe or conductor 24 and being exhausted from the steam chestat the other in the machine through a similar pipe or mniluctor 25communicating with the pipe 9:).

The upper series of rollcrsor drums are driven by a sprocket chain .27engaging the sprocket:- whecls to, while the lower set or series ofrollers 9, are driven by frictional contact with the paper strip as thelatter passes througn the mach ne.

One of the drums or rollers 8 of the upper series 'is provided with arelatively large sprocket wheel 28, which latter is connected throughthe medium of a sprocket chain 29 with a motor engine or other source ofpower, thereby to rotate the several feed rollers or drums.

A sprocket chain 30 engages the teeth of the-sprocket'wheels 16 on thelower set or series 9 in order that said rollers may rotate in unison.

Extending laterally and upwardly from vone end of the machine, arespaced brackets 31 having terminal bearings 32, in which is journaled aspool or spindle 33 carrying a roll of facing paper 34, which latter isfed throught-he machinetogether with the corrugated strip 35 and securedto the latter in order to produce the composite sheet, indicated at 36.r f

Disposed beneath the spool carrying bracket 31, is a second bracket 37,to which is secured in any suitable manner, a paste l l I cup or tank33. Mounted for rotation within the paste cup or tank 38 and ournaled insuitable bearings :39 in the bracket 57, 1s a roller 40'which appliesthe paste or other adhesive material in the cup to the adjacent faceofthe corrugated strip 35 as the latter is fed through the machine.Journaled in bca rings in the lower portion of the bracket 37, are aplurality of feed rollers 41, each having one end thereof extended toform a spindle 42, to which is secured a sprocket wheel 43. A sprocketchain 4-1 engages the sprocket wheel -13 of the feed rollers and alsobasses around a sprocket wheel +5 on the spindle of the paste applyingroller 40, the latter being provided with a similar sprocketwheel at)which engages the sprocketchain 27 so that motion may be transmittedthrough the medium of the sprocket chain 2-? to the pas e applyingroller 40 and thence through the medium of the chain 41 to the feedrollers 41, as best shown in Fig. 1 of the drawings.

The supporting feet or legs at the front of the machine are extendedlaterally and provided with horizontally alined bearings -17, in whichis mounted for rotation a transverse shaft -13 having spaced eccentrics49 secured to the opposite ends thereof and which co-act with suitableeccentric straps 50.

Mounted for oscillation on the shaft 48, is a'franv), the side bars oiof which are pivotally mounted at their lower ends on the shaft 48,while their upper ends are. formed with vertically disposed slots 52, inwhich is mounted a reciprocating cutting blade or knife 53. The oppositeends of the cutting blade 53 are reduced and projected through the 57 52for connection with vertically disposv ods 54, said rods forming aconnection between the eccentric straps 50 and the opp-site ends of thecutting blades as best shown in Fig. 5 of the drawings. Connecting thebars 51 of the oscillating frame beneath the slots 52, is a bed plate 55which coach; with the knife 53 to cut or sever the composite strip intopredetermined lengths.

Motion is imparted to the oscillating frame 51 by means of an arm 56,one end of which is secured to the adjacent side bar of the frame 51,while the other end thereof extends above the sprocket chain 31 and isprovided with a terminal lip or finger 57. which latter extends into thepath of move ment of an actuating finger or lug 58 carried by thesprocket chain 30. Thus it will be seen that as the sprocket chain 30rotates, the pin or lug 58 will intermittently engage the finger 57 ofthe arm 56 and force the oscillating frame 51 laterally to the dottedline pos tion shown in Fig. 1 of the drawings, said oscillating framebeing returned to normal or vertical position by means of a (2011 spring59 operatively connected withthe frame 51 and supporting frame 5.

*shoosely mounted for rotation on one end of the transverse shaft 48, isa wheel or pulley 00, over which travels a belt 61 leading to a motor orother suitable source of power for actuating the cutting blade 53.

The inner face of the wheel or pulley (S0 is provided with a clutchmember 62, there being a similar clutch member (53 keyed to the shaft 48and adaptcdto engage the mating clutch member (3:2 for transmittingmotion from the pulley GO to the shaft 48.

livotally monnted at 64 on one of the side members of the oscillatingframe 51, is a lever (35, one end of which is bifurcated for engagementwith the movable clutch member 03 so that when the lever is tilted, theclutch members (32 and 63 will be moved into and out of engagement witheach other.

The free end of the operating lever 65 travels in the path of aninclined bar or cam 66 carried by the supporting frame 5 so that whenthe oscillating frama 51 is swung latorally away from the machine, thelever 65, by engagement with the cam 66, will actuate the clutchmembersto key the pulley (30 on the shaft 48, thereby to actuate theknife and cut or sever a predetermined length of the composite strip.

In order to disengage the clutch members 62 and 63 after each downwardmovement of the knife 53, there is provided a spring (37, one end ofwhich is secured to the lever 65, while the opposite end thereof issecured to one of the side members of the frame 51. Thus it will.- beseen that when the lug 58 engages the lip on the arm 56, the oscillatingframe 51 will be swung laterally, thereby causing the cam 66 to trip thelever 65 and throw the clutch members 62 and 63 into engagement witheach other and rotate the shaft 48 A- the shaft 48 rotates, thecoccntrics49 will actuate the rods 54 to lower the cutting blade 53 inthe direction of the plate 55 and cut or sever the composite strip.After the lug 58 is disengaged from the arm 5! the spring 59 willautomatically return the frame 51 to normal or vertical position, and indoing so cause the cam 66 to actuate the lever 65 and disengage theclutch members 03 so that the cutting mechanism will remain dormant.until the lug 58 again engages the finger on the arm 56, in the mannerbefore stated.

The casing or housing 7 is preferably lined with a jacket of asbestos68, while the top of the casing is provided with a pivoted cover 69 sothat access may be read1ly.had

to the interior of the casing to effect any necessary repairs to thefeed rollers and steam chests.

' In operation, the corrugated strip having a single facing appliedthereto, is fed through the corrugatmg machine or from a suitable drumocteel. to the feed rollers? 41 and thence ever the roller 40 and idleroller 70, the roller 40 applying the paste or other adhesive materialto the corrugated side of the strip during its passage to the feedrollers 8 and 9. As the corrugated strip 35 having single facing appliedthereto, is fed between the upper and lower series of feed rollers 25and t), the facing strip 34, by frictional engagement with the strip 35,will be withdrawn from the spool 33 and forced in contact with theadhesive material on the corrugated strip 35, the steam in the feedrollers 2'5 and S) and steam chests 22, serving to dry the adhesivematerial as said strips are pressed together so as to form a compositestrip comprising acorrugated body portion having its opposite sidescovered with a facing of paper. As the compositc strip is fed throughthe front of the machine, the arm 50, by engagement with the lug 58,will intermittently actuate the cutting device to cut or sever saidcomposite strip into predetermined lengths, which strips may be piled ona table or other support 71 designed to receive the same.

By changing the position of the lug 58 on the sprocket chain 30, or bylengthening or shortening the arm 56, the lengths of the strlips ofcomposite paper may be varied at "M If desired, one of the sprocketchains 30 may be used on each side of the machine, and in some cases,the clutch members 62 and 03 may be actuated manually lnstead of.
